提出Deep Adaptive Graph Neural Network (DAGNN) 当感受域增大时,来自适应的接收领域信息。2 Empircial and theoretical analysis of deep GNNs大多数流行的图卷积操作遵循邻域聚合(或消息传递)的方式,通过传播(propagating)相邻节点的表示并随后应用转换来(transformation)学习节点表示。一般图卷积的第 ll 层可以描述为...
Introduction 在GNN中使用多层的网络会出现过度平滑的问题(over-smoothing),过度平滑即是不同类的点特征趋近于相同,导致无法分类。 出现过度平滑的问题,主要是由于representation transformation 和 propagation的entanglement(纠缠) Analysis of Deep GNNS 定量的分析节点特征的平滑值 SMVgSMVg就是整张图的平滑度值,SMVgSM...
Overlapping Community Detection with Graph Neural Networks 论文: Overlapping Community Detection with Graph Neural Networks. 源码: https://github.com/shchur/overlapping-community-detection 文章概述 现有的用于社团检测的神经网络只检测不相交的社区,而真实的社区却是重叠的,针对这一不足,提出了一种基于GNN的重...
In this work, we study this observation systematically and develop new insights towards deeper graph neural networks. First, we provide a systematical analysis on this issue and argue that the key factor compromising the performance significantly is the entanglement of representation transformation and ...
3、Graph Embedding Algorithm In this section, we introduce the first-order graph and second-order graph of network traffic, then propose the graph embedding algorithm for these two graphs. At last, we also adopt two optimization methods to reduce the complexity of the proposed algorithm. ...

Digging a bit deeper Collecting large amount of data with labels is expensive and time consuming. On the other hand, unlabeled images are available in a vast amount and are easy to collect. So naturally we’d like to utilize this data for training deep learning models. Some previous work...
This is conformal with the understanding that deeper networks tend to be more accurate. However, as complexity grows, the latter statement is valid if there is enough representative data being provided in the training phase. If the number of observations is reduced, larger networks will be more ...
